Which main class is associated with electrical hazards?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (C)

Electrical fires are categorized as Class C because electricity is the primary hazard in those fires. The designation recognizes that the danger comes from energized equipment, not just the fuel feeding the fire. If it’s safe to do so, power should be cut to remove the electrical hazard, and a non-conductive extinguishing method should be used. Once the power is off, the fire may be reclassified based on the fuel involved. The other classes cover different hazards: Class A for ordinary combustibles, Class B for flammable liquids, and Class D for combustible metals.
